Hi Dan,

Just tell me were to upload it :-)

Funny thing is, this was happening by just connecting to a share, not even browsing or putting file activity on it

Kr,

There were some SMB updates in r151016.

There are even BIGGER ones that landed in illumos just after 016 closed, so I don't have a handy reference from upstream.

Looking at '016, your problem is likely in a function whose frame isn't in your dump:  smb_sign_begin().  There are two potential bcopy() calls there, and one of them is calling with a NULL pointer.

        bcopy(token->tkn_session_key, sign->mackey, SSN_KEY_LEN);
        if (sinfo->ssi_cspwlen > 0) {
                bcopy(sinfo->ssi_cspwd, sign->mackey + SSN_KEY_LEN,
                    sinfo->ssi_cspwlen);
        }

I'm not sure which of those two gets called.

Having said that, I'm not sure how much help I can get or give you without an actual coredump to inspect.
